New Cars with a Turbo and Start Stop

[boat_guy64]

I hate start/stop. I turn it off. When I forget, I always notice a lag in the power steering being powered on. They also claim it won't shut off in the winter when the car is cold. They lie. It does. This feature came into play because a former administration imposed gas mileage limits. This was a cheat by the car companies to achieve them.

As far as turbos. I've had two trucks with turbos. I was really worried about going form a V8 to a turbo charged motor. I tow often. Happy to report that I've had no issues and I get better gas mileage and more torque than I had with my V8.

The first time I ever drove a car with start/stop it was a rental and I had no idea such a thing existed until I was in the typical massive traffic on the George Washington bridge and the stupid thing kept shutting off. This has to be one of the all time stupidest things ever inflicted on the public. Sure the car starts right up, usually. But what if it doesn't or what happens when the car has 85000 miles on it and is a little tired and takes a few cranks to start?

The second worst thing is the keyless start. Is it really that hard to put in the key and turn it on? I don't know how many times I have walked away and left the car running. The key got locked inside once and another time I left the car running on purpose because it was cold and my mom was in the car but apparently it shuts off if the key gets out of range.

No thanks to any of this crap.

The doors are not suppose to lock on a keyless start if the keys are left in it?

so they told me, but there I was out in the middle of Wonalancet with the key on the seat. Call me old but I want nothing to do with 90% of all the new "features" forced into cars. I drive rentals a lot when I travel and have a long list of cars I hate.

I don't like them either but at some point I think they will all be keyless. I'm a life long customer of Chevy Silverado pick ups but I read that in 2022 they will be going keyless and shifterless and I'm not happy about it!

I’ll never own a car again with out keyless entry/start again... leave the keys in my pocket I walk right up and the doors unlock, push button to start... great, Y’all living in 1990

Gasoline turbos aren't new. I had a 1984 Volvo turbo. Great car, traded it at 85000 miles when I needed a van for a wheelchair. I don't have s/s, but my friend has start/stop. Aggravating, mostly shuts it off. For many years, I mostly drove convertibles, so I rarely locked the car anyway. The fob is harder to carry when you normally have a key ring with a dozen keys. My office has a fob security system, better security and you can just reprogram the locks when somebody joins or leaves, but I'd rather a keypad instead of something I have to carry, whether building or car.

I love the start, stop. My significant other hates it. It's funny how you either love it or hate it. I love the keyless too. My old car doesn't have it and I am always hunting for the key to put in the ignition.

We bought a Chevy Equinox with the 2L turbo last year. It is a peppy car and we liked the performance during the test drive. It was great until we got it home and when reading the manual discovered it ran on 93 octane gas. It gets good gas mileage but the cost per mile isn't that much better than my Silverado which runs fine on 87 octane. It's my fault for not knowing this before but it should probably have been mentioned by the salesperson. I've heard other turbos need high test too so it's something to consider.

That seems like a big annoyance around here. 93 Octane is not available at most gas stations. I'd hate to be driving around and not only have to keep track if I am getting low on fuel but also WHERE I might be able to get it and whether I have enough gas remaining to get there.

We've never had a problem getting 93 octane. I understand 91 works ok but is not optimal. It's a good thing that we haven't had issues as the tank is small and we seem to fill up more than we'd like.

I wonder if all that Start/Stop does a number on the starter ?

I wonder that too. And you would think the starting and stopping would create worse fuel economy not better.

[jeffk]

Many of the components have to be beefed up to handle the stresses of repeated stops/starts and remain reliable. Further, some systems that ran off belts, for example A/C compressor & water pump, need to be changed over to be powered by an electrical motor. That also requires a beefed up battery to power these systems while the engine is stopped. In fact, if the battery is low, the start/stop may not activate. Then you need all the monitoring and management systems to keep it all coordinated.

While it is likely that the beefed up systems, like a starter, will last as long as a normal system component, it will cost more to replace the beefed up and possibly more complex component.

As it turns out, the cost in fuel to restart is insignificant once the car is warmed up.

And the reason for all this is to cut down on a bit of pollution and save a little gas. However, this may be gaming the system because the energy and pollution to produce all these beefed up components plus the energy costs to carry the extra weight of them around through the lifetime of a car might offset the benefit of stopping the engine for a bit. Plus it adds to the costs of recycling the bigger components at end of life. No one wants to take a hard look at that because it's an ugly truth. Manufacturers needed to cut pollution and get better gas mileage which government tracks but they added downside costs to other parts of car ownership that no one pays attention to. Just because it isn't monitored doesn't mean it is a net positive.

On top of all this, it simply costs more. If there was a positive accomplishment for the cost, maybe it would be worth it. But we may be paying more simply to play regulation games of no ultimate value.

Another fuel economy inspired issue is the automated fuel management system in my Silverado. Whenever possible the engine drops from six cylinders to four. It's supposed to be a seamless transition from 6 to 4 and back to 6 cylinders. I get a sluggishness when transitioning back and after 5 trips to the dealer they said it was normal and I had to live with it. I'm almost used to it after 5 years.

Are there other engine options, or do all Silverados have the auto fuel management?

I'm not sure what is offered now but AFM came with the 6 and 8 cylinder engines.

Maybe it is different in the 6 cylinder vehicles. I have it in two Tahoes (2007 and 2019) and a 2020 GM sportscar with the 6.2 V8. I cannot even tell when the engine transitions from 8 cylinders to 4 cylinders and back. The only way I know it is happening is the V4 and V8 indicator on the dashboard.

The need for high octane was one of the reasons I chose an NA engine in my one full-sized pickup, though I believe many of the new T/SC vehicles with direct injection run fine on regular.
